iNetVideo has had bluray steelbooks on sale in the past, but I think the prices are a little better in this sale -
There are some good titles on sale including -
Gangs of New York
There are a total of 20 on sale and most are $19.99, a few are higher. The prices seem to be substantially lower than Amazon, but I didn't check all of them.
Remember that iNetVideo has a sliding scale shipping policy. The first two items are $2.50 each, then the price declines to $1 for each item, so it makes sense to order as much as you want in one order to average down the shipping costs (be sure to check on the website to see what else is on sale). They have had coupons that discount shipping in the past, but I don't know if any are available at this time.
